array_unshift — Prepend one or more Elements to the beginning of an array.

array_unshift() prepends passed elements to the front of the array. Note that the list of elements is prepended as a whole, so that the prepended elements stay in the same order. All numerical array keys will be modified to start counting from zero while literal keys won’t be changed.
